Continuously variable transmission system employing segmented pulleys
Abstract
Abstract A MECHANICAL TRANSMISSION SYSTEM INCLUDES AXIALLY PARALLEL CONICAL MEMBERS ON WHICH ARE LONGITUDINALLY ABLE PULLEY SEGMENTS CONSTITUTING COMPOSITE PULLEYS DRIVINGLY ENGAGED BY ONE OR MORE DRIVE BELTS. SIMULTANEOUS MOVEMENT OF THE PULLEY SEGMENTS AND BELT CHANGES THE RATIO OF PULLEY DIAMETERS AS THE PULLEY SEGMENTS MOVE LONGITUDINALLY AND RADIALLY OF THE CONICAL MEMBERS. MEANS FOR SHIFTING THE PULLEY SEGMENTS AND BELT SIMULTANEOUSLY IS PROVIDED. A DRIVE MOTOR AND DRIVEN LOAD CAN BE COUPLED TO THE CONICAL MEMBERS. CONTROL MEANS RESPONSIVE TO THE MAGNITUDE OF POWER DRAWN BY THE DRIVE MOTOR IN RESPONSE TO CHANGE IN THE LOAD AUTOMATICALLY ACTUATES THE SHIFTING MEANS TO POSITION THE PULLEY SEGMENTS FOR SETTING AN OPTIMUM RATIO OF PULLEY DIAMETERS.
